      Certain statements made in this Annual Report on Form 10-KSB are
"forward-looking statements" (within the meaning of the Private Securities
Litigation Reform Act of 1995) regarding the plans and objectives of management
for future operations. Such statements involve known and unknown risks,
uncertainties and other factors that may cause actual results, performance or
achievements of the Company to be materially different from any future results,
performance or achievements expressed or implied by such forward-looking
statements. The forward-looking statements included herein are based on current
expectations that involve numerous risks and uncertainties. The Company's plans
and objectives are based, in part, on assumptions involving the continued
expansion of business. Assumptions relating to the foregoing involve judgments
with respect to, among other things, future economic, competitive and market
conditions and future business decisions, all of which are difficult or
impossible to predict accurately and many of which are beyond the control of the
Company. Although the Company believes that its assumptions underlying the
forward-looking statements are reasonable, any of the assumptions could prove
inaccurate and, therefore, there can be no assurance that the forward-looking
statements included in this Report will prove to be accurate. In light of the
significant uncertainties inherent in the forward-looking statements included
herein, particularly in view of the Company's early stage operations, the
inclusion of such information should not be regarded as a representation by the
Company or any other person that the objectives and plans of the Company will be

General

      The Company develops, manufactures, markets and sells equipment and
related disposable or consumable items and other products for use primarily by
the dental practitioner. Company products focus on practitioner efficiency,
patient comfort, and infection control. The Company's principal product is the
"The Wand(R)", (a computer controlled "painless" injection system enabling the
practitioner to more quickly and effectively anesthetize patients in certain
dental applications), which the Company introduced at the Fall 1997 American
Dental Association Trade Show. The Company began selling equipment units of "The
Wand(R)" and an initial supply of disposables in January 1998. "The Wand(R)" was
originally sold in the U.S. and Canada through major distributors of dental
products. A toll free number was established in January 1999, allowing dentist
to buy the product directly from the Company.

      In October 1999, the Company launched its new disposable handpiece, the
Wand(R) Plus. The product reduced the aspiration time from 14 to 5 seconds. In
conjunction with the launch of the Wand(R) Plus handpiece, the Company severed
the U.S. dealer distribution channel and began selling its product directly to
dentists throughout the U.S. The dealer distribution channel in Canada was not
affected.

      In January 1999, the Company received authorization to apply the CE mark
to "The Wand(R)." This is a requirement for all dental and medical devices
distributed throughout the European Union. In September 1999, the authorization
was extended to include medical use of "The Wand(R)". Furthermore, in February
1999, the Company entered into an agreement for the international distribution
of "The Wand(R)". In January 2000, the Company entered into an agreement to
terminate its existing international distribution agreement and commenced new
international distribution agreements, giving its products entry into Japan,
Great Britain, Germany, Israel, South Africa, Scandinavia, while retaining its
presence in China and Taiwan.

      The Company also markets and sells (i)"SplatrFree(TM)" disposable prophy
angles and (ii) luer lock needles. Both are currently being sold domestically,
directly to its dental customers.

      The Company was organized in August 1989 under the laws of Delaware. On
November 3, 1995, the Company acquired 65% of the outstanding shares of common
stock of Spintech for an aggregate purchase price of $2,700,000. During 1998 and
1999, the Company increased its interest in Spintech to 75.9% by exchanging
shares of Milestone Common Stock for Spintech shares and by exercising the
second and third of a series of five annual options to acquire an additional 3%
of Spintech's shares for a nominal amount granted in the original acquisition
transaction. Spintech developed and owns the technology underlying various
products for healthcare providers, including "The Wand(R)" and has registered
various patents and trademarks related to these products.

      The Company maintains its executive offices at 220 South Orange Avenue,
Livingston Corporate Park, Livingston, New Jersey 07039, and its telephone
number is (973) 535-2717.

Products

      "The Wand(R)" Computer Controlled Anesthetic Injection System is a
computer controlled local anesthetic delivery system developed by the Company.
The Company believes "The Wand(R)" overcomes the typical problems of
conventional anesthetic injections. "The Wand's(R)" slim pencil-like shape is
more functional to the user and less ominous in appearance to the patient. The
pencil grip provides a greater level of stability for the user by preventing
antagonistic movements between the patient and the practitioner during needle
placement, a positioning control not possible with syringes currently in use. A
computer driven infusion machine operated by the standard air controlled foot
pedal provides the precision flow necessary for virtually painless local
anesthesia. "The Wand(R)" provides a highly controlled rate of emission of
anesthetic solution in advance of the needle point. The anesthetic and the
controlled rate of fluid emission causes an anesthetic pathway which numbs the
tissue immediately ahead of the needle's entry. The controlled rate
substantially eliminates the so-called "bee sting" effect, which is pain
associated with the sudden build-up of pressure by the too rapid flow rate of
expelled fluids. Because "The Wand(R)" uses a disposable handpiece and needle,
the Company believes it will offer protection against patient
cross-contamination.

      In many procedures, "The Wand(R)" more quickly anesthetizes by eliminating
the need for preliminary pain blocking injections and the waiting time required
to see if this injection has taken effect before further anesthetic injections.
Also, with the October 1999 introduction of the Wand(R) Plus disposable
handpiece, the aspirating time was reduced from 14 to 5 seconds. The Company
believes that "The Wand(R)" enables a dentist to provide virtually painless
injections, increase productivity, be more sanitary and will provide important
competitive advantages for dentists trying to build and maintain their
practices. While designed for use in dentistry, "The Wand(R)" may also have uses
in proctology, podiatry, urology and possibly dermatology and plastic surgery.
Although the Company has mainly focused its marketing of "The Wand(R)" on the
dental market, it was also granted approval in September 1999 to sell "The
Wand(R)" in Europe for medical use.

      Although many dentists often give comfortable injections, it is extremely
difficult for them to do so consistently using conventional techniques. Dentists
do not have a strong purchase point against which they may guide their hand when
inserting a needle or while making the injection. The resulting uncontrolled
movement of the needle frequently can be painful to the patient. Although the
dentist is taught to inject slowly, present devices do not allow automatic
control of the rate of flow. Thus, the needle often enters tissue which has not
yet been anesthetized. "The Wand(R)" can precisely control the flow rate and
modulate fluid pressure by the use of a microprocessor and electronically
controlled motor.

      The Company began shipping system kits consisting of "The Wand(R)" driver
unit, an initial supply of disposable handpieces, an instructional video tape
and other instructional material in January 1998. Prior thereto pre-production
prototype of "The Wand(R)" has been clinically tested in over 1,000 patients.
Ninety-six percent of those tested reported a "painless" or significantly less
painful procedure than standard procedures clinical. Three separate additional
clinical studies were conducted on various aspects of "The Wand(R)" operation
and were published in major dental publications. Over the last two years, three
favorable evaluations were reported by independent testing groups. Also, eight
domestic and three international studies were completed in 1999 and submitted
for publication in major dental journals.

      "SplatrFree(TM)" Prophy Angles. Prophy angles are dental drill accessories
incorporating a cup-like tip moving at high rotational speeds which are used by
dentists and dental hygienists in teeth cleaning and other prophylaxis
procedures. Prophy angle tips frequently cause splattering of saliva,
particulate matter and possibly pathogens onto the dentist, hygienist, dental
tools and surrounding surfaces. The "SplatrFree(TM)" prophy angle has a unique
tip design that substantially eliminates splattering. The "SplatrFree(TM)"
prophy angle is available in disposable models. The Company believes that its
prophy angle can improve dental office infection control and hygiene by reducing
the spread of infection from patient to patient and from patient to dentist or
hygienist.

      Since the Company began marketing "the Wand(R)," it has included Becton
Dickinson Luer Lock Needles in its wand system kits. In October 1999, the
Company began selling the needles directly to its dental customers.

Manufacturing and Sources of Supply

      "The Wand(R)" equipment units are manufactured for the Company by Tricor
Systems, Inc. ("Tricor") pursuant to specific purchase orders. In order to fund
certain expenses of Tricor, the Company has continued to advance funds to
Tricor. These advances are reduced as Tricor makes shipments to the Company. Net
advances to Tricor as of December 31, 1999 and 1998 were $1,707,789 and
1,796,400, respectively. The Company has received a security interest in certain
Tricor assets.

      The disposable handpiece for "The Wand(R)" is manufactured for the Company
by Nypro Inc. ("Nypro") pursuant to scheduled production requirements. Nypro
utilizes molds, semi-automated assembly equipment and packaging equipment
purchased by the Company. In 1998, a $1,712,982 writedown of new, yet unused,
semi-automation equipment and molds was made by the Company. The semi-automation
equipment and molds were purchased for approximately $2,200,000 in anticipation
for the ramp up of disposable handpiece sales.

      All "SplatrFree(TM)" prophy angles have been produced for the Company by
Team Technologies, Inc. ("TTI") pursuant to an agreement entered into in July
1995. Prototype prophy angles were produced in a single cavity mold purchased by
the Company for $7,000. Commercial quantities of prophy angles are produced
utilizing a 16-cavity production mold capable of producing more than 30,000
prophy angles per day. The 16-cavity production mold was purchased by the
Company at a cost of $72,000. Commercial delivery of prophy angles began in the
first quarter of 1997 after small modifications to TTI production molds.

      In October 1999, the Company reached an agreement through an authorized
intermediary to sell Becton Dickinson ("BD") Luer Lock Needles directly to
Milestone dental customers. In December 1999, the Company was informed by BD
that its dental partner, Crosstex International would handle future purchases by
the Company.

Marketing

      "The Wand(R)" was originally marketed to dental practitioners through a
group of dental distributors in the U.S. and Canada. In October 1999 and in
conjunction with the launch of The Wand(R) Plus handpiece the Company severed
the U.S. distribution channel and began selling and marketing its product
directly to dentists throughout the U.S. The dealer distribution channel in
Canada was not affected. In addition, the Company has established regional sales
territories in the U.S. and in Canada. As of December 31, 1999, these
territories were staffed by two full time sales people and three independent
sales representatives. Sales representatives train, motivate, and direct sales
activity. They also conduct study clubs for dentists, contact and call on dental
hygiene schools, attend local, state and national dental conventions and call on
dentists for training and education purposes. Sales literature and training
materials are produced to support the selling and educational activities of
Company and its representatives. Currently, the company has ten full time sales
people and five independent sales representatives.

      Marketing of the Wand(R) outside the U.S. and Canada is accomplished
through specified dental product distributors. AFP Imaging ("AFP") who
originally identified these distributors, is phasing out its involvement.

      The Company markets its other products directly to its dental customers.


                                       6

Dental and Hygiene School Program

      The Company has a commitment to the dental profession to support the
education and training of future dentists and dental professionals. Accordingly,
the Company offers special educational assistance programs to qualified dental
and hygiene schools throughout the United States and Canada. These programs
include providing demo units, a year supply of handpieces per unit, and free
instruction and guidance to participating educators. Currently, the Wand(R) has
been added to the curriculum of 28 U.S. and Canadian dental schools and 16
schools providing degrees in dental hygiene.

Competition

      The Company faces intense competition from some companies in the medical
and dental device industry, including well-established academic institutions,
possessing substantially greater financial, marketing, personnel, and other
resources. Most of the Company's competitors have established reputations,
stemming from their success in the development, sale, and service of medical
products. Further, rapid technological change and extensive research and
development characterize the industry. Current or new competitors could, at any
time, introduce new or enhanced products with features that render the Company's
products less marketable, or even obsolete. Therefore, the Company must devote
substantial efforts and financial resources to enhance its existing products, to
bring its developmental products to market, and to develop new products for its
related markets. In order to compete successfully, the Company must establish an
effective distribution network. Several regulatory authorities must also approve
the Company's products before they may be marketed. There can be no assurance
that the Company will be able to compete successfully, that its competitors will
not develop technologies or products that render the Company's products less
marketable or obsolete, or that the Company will be able to successfully enhance
its existing products, effectively develop new products or obtain required
regulatory approvals therefor.

      "The Wand(R)" competes with non-automated disposable and reusable syringes
and other local anesthetic delivery systems generally selling at significantly
lower prices and utilizing established and well-understood methodologies. "The
Wand(R)" competes on the basis of its performance characteristics and offers
significant benefits to the dentist and the patient. It reduces fear, pain and
anxiety for the patient and greatly reduces dentist stress levels. It can be
used for all local anesthesia techniques as well as new and modified techniques.
These new techniques allow faster procedures, shortening of chair time while
minimizing numbing of the lips and facial muscles of expression. It enhances
productivity, reduces stress and virtually eliminates pain and anxiety.

      "SplatrFree(TM)" prophy angles competes with prophy angles produced and
distributed by a number of major manufacturers and distributors and other
producers or distributors of dental products, many of whom have significant
competitive advantages because of their size, strength in the marketplace,
financial and other resources and broad product lines. The Company competes on
the basis of the superior, non-splattering performance of its prophy angle and
product quality.

      The luer lock needle competes with dental needles produced and distributed
by a number of major manufacturers and distributors and other producers or
distributors of dental products, many of whom have significant competitive
advantages because of their size, strength in the marketplace, financial and
other resources and broad product lines. The Company competes on the basis of
convenience since it can package the product with an order for disposable
handpieces.

Patents and Intellectual Property

      The Company's patents are believed to be material to its business and
potential growth. The Company holds the following nine United States patents:

      The Company has also filed two additional United States utility patent
applications on improvements in "The Wand(R)" and its accessories, and two other
utility applications on related injection technology. There are also three
pending design patent applications on various component parts of "The Wand(R)".
Those applications are presently awaiting examination at the United States
Patent and Trademark Office.

      The Company has adopted the trademarks "SplatrFree(TM)", "The Wand(R)" and
"The Wand(R)Plus." "SplatrFree(TM)" is registered on the Supplemental Register
as United States Trademark Registration No. 2,226,868, issued February 23, 1999.
"The Wand(R)" is registered on the Principal Register as Registration No.
2,291,401, issued November 9, 1999. "The Wand(R)Plus" is the subject of a
pending trademark application which is awaiting action at the United States
Patent & Trademark Office.

      The Company relies on a combination of patent, copyright, trade secret,
and trademark laws and employee and third-party nondisclosure agreements to
protect its intellectual property rights. Despite the precautions taken by the
Company to protect its products, unauthorized parties may attempt to reverse
engineer, copy, or obtain and use its products and other information the Company
regards as proprietary. Litigation may be necessary to protect the Company's
intellectual property rights and could result in substantial cost to, and
diversion of effort by, the Company with no guarantee of success. The failure of
the Company to protect its


                                       8
<PAGE>

proprietary information, and the expenses of doing so, could have a material
adverse effect on the Company's operating results and financial condition.

      While there are no current claims that the Company's products infringe on
the proprietary rights of third parties, there can be no assurance that third
parties will not assert infringement claims against the Company in the future
with respect to current or future products or that any such assertion may not
require the Company to cease selling such products, or to enter into
arrangements that require the Company to pay royalties, or to engage in costly
litigation. Although the Company has received no claims of infringement, it is
possible that infringement of existing or future patents or proprietary rights
of others may occur. In the event that the Company's products infringe patent or
proprietary rights of others, the Company may be required to modify its
processes or to obtain a license. There can be no assurance that the Company
would be able to do so in a timely manner, upon acceptable terms and conditions,
or at all. The failure to do so would have a material adverse effect on the
Company.

Government Regulation

      "SplatrFree(TM)" prophy angles and "The Wand(R)" were cleared for
marketing in the United States by the FDA in April and July 1996, respectively.

      The manufacture and sale of medical devices and other medical products,
such as the "SplatrFree(TM)" prophy angle and "The Wand(R)", are subject to
extensive regulation by the FDA pursuant to the FDC Act, and by other federal,
state and foreign authorities. Under the FDC Act, medical devices must receive
FDA clearance before they can be commercially marketed in the United States.
Some medical products must undergo rigorous pre-clinical and clinical testing
and an extensive FDA approval process before they can be marketed. These
processes can take a number of years and require the expenditure of substantial
resources. The time required for completing such testing and obtaining such
approvals is uncertain, and FDA clearance may never be obtained. Delays or
rejections may be encountered based upon changes in FDA policy during the period
of product development and FDA regulatory review of each product submitted.
Similar delays may also be encountered in other countries. Following the
enactment of the Medical Device Amendments to the FDC Act in May 1976, the FDA
classified medical devices in commercial distribution into one of three classes.
This classification is based on the controls necessary to reasonably ensure the
safety and effectiveness of the medical device. Class I devices are those
devices whose safety and effectiveness can reasonably be ensured through general
controls, such as adequate labeling, premarket notification, and adherence to
the FDA's Quality System Regulation ("QSR"), also referred to as "good
manufacturing practices ("GMP") regulations. Some Class I devices are further
exempted from some of the general controls. Class II devices are those devices
whose safety and effectiveness can reasonably be ensured through the use of
special controls, such as performance standards,post- post-market surveillance,
patient registries, and FDA guidelines. Class III devices are devices which must
receive premarket approval by the FDA to ensure their safety and effectiveness.
Generally, Class III devices are limited to life-sustaining, life-supporting or
implantable devices.

      If a manufacturer or distributor can establish that a proposed device is
"substantially equivalent" to a legally marketed Class I or Class II medical
device or to a Class III medical device for which the FDA has not required
premarket approval, the manufacturer or distributor may seek FDA marketing
clearance for the device by filing a 510(k) Premarket Notification. The 510(k)
Premarket Notification and the claim of substantial equivalence may have to be
supported by various types of data and materials, including test results
indicating that the device is as safe and effective for its intended use as a
legally marketed predicate device. Following submission of the 510(k) Premarket
Notification, the manufacturer or distributor may not place the device into
commercial distribution until an order is issued by the FDA. By regulation, the
FDA has no specific time limit by which it must respond to a 510(k) Premarket
Notification. At this time, the FDA typically responds to the submission of a
510(k) Premarket Notification within 90 to 200 days. The FDA response may
declare that the device is substantially equivalent to another legally marketed
device and allow the proposed device to be marketed in the United States. The
FDA may, however, determine that the proposed device is not substantially
equivalent, or may require further information, such as additional test data,
before the FDA is able to make a


                                       9
<PAGE>

determination regarding substantial equivalence. Such determination or request
for additional information could delay the Company's market introduction of its
products and could have a material adverse effect on the Company. If a device
that has obtained 510(k) Premarket Notification clearance is changed or modified
in design, components, method of manufacture, or intended use, such that the
safety or effectiveness or the device could be significantly affected, separate
510(k) Premarket Notification clearance must be obtained before the modified
device can be marketed in the United States.

      If a manufacturer or distributor cannot establish that a proposed device
is substantially equivalent, to a legally marketed device, the manufacturer or
distributor will have to seek premarket approval of the proposed device. A
premarket approval application (a "PMA application") would be supported by
extensive data, including pre-clinical and human clinical trial data, as well as
extensive literature, to prove the safety and efficacy of the device. Upon
receipt, the FDA will conduct a preliminary review of the PMA application to
determine whether the submission is sufficiently complete to permit substantive
review. If sufficiently complete, the submission is declared acceptable for
filing by the FDA. The FDA has 180 days to review a PMA application once it has
been declared acceptable for filing. While in the past the FDA has responded to
PMA applications within the allotted time period, more frequently PMA reviews
occur over a significantly protracted time period, and generally take
approximately two years or more from the date of filing to complete. A number of
devices for which FDA marketing clearance has been sought have never been
cleared for marketing.

      If human clinical trials of a proposed device are required and the device
presents "significant risk," the manufacturer or distributor of the device will
have to file an Investigational Device Exemption ("IDE") application with the
FDA prior to commencing human clinical trials. The IDE application must be
supported by data, typically including the results of animal and mechanical
testing. If the IDE application is approved, human clinical trials may begin at
the specific number of investigational sites and could include the number of
patients approved by the FDA subject to any limitations imposed by FDA, such as
the specific number of investigational sites and/or number of patients approved
by FDA.

      Though the "SplatrFree(TM)" prophy angle and "The Wand(R)" have received
FDA clearance based on its 510(k) Premarket Notification, there can be no
assurance that any of the Company's other products under development will obtain
the required regulatory clearance on a timely basis, or at all. If regulatory
clearance of a product is granted, such clearance may entail limitations on the
indicated uses for which the product may be marketed. In addition, modifications
may be made to the Company's products to incorporate and enhance their
functionality and performance based upon new data and design review. There can
be no assurance that the FDA will not request additional information relating to
product improvements, that any such improvements would not require further
regulatory review thereby delaying the testing, approval and commercialization
of the Company's development products or that ultimately any such improvements
will receive FDA clearance.

      Compliance with applicable regulatory requirements is subject to continual
review and will be monitored through periodic inspections by the FDA. Later
discovery of previously unknown problems with a product, manufacturer, or
facility may result in restrictions on such product or manufacturer, including
fines, delays or suspensions of regulatory clearances, seizures or recalls of
products, operating restrictions and criminal prosecution and could have a
material adverse effect on the Company.

      The Company is subject to pervasive and continuing regulation by the FDA
regulations which require manufacturers of medical devices to adhere to certain
QSR requirements also referred to as "Good Manufacturing Practices" ("GMP") as
defined by the FDC Act. QSR compliance requires testing, quality control and
documentation procedures. Failure to comply with QSR requirements can result in
the suspension or termination of production, product recall or fines and
penalties. Products must also be manufactured in registered establishments. In
addition, labeling and promotional activities are subject to scrutiny by the FDA
and, in certain circumstances, by the Federal Trade Commission. The export of
devices is also subject to regulation in certain instances.


                                       10
<PAGE>

      The Medical Device Reporting ("MDR") regulation obligates the Company to
provide information to the FDA on product malfunctions or injuries alleged to
have been associated with the use of the product or in connection with certain
product failures which could cause serious injury. If, as a result of FDA
inspections, MDR reports or other information, the FDA believes that the Company
is not in compliance with the law, the FDA can institute proceedings to detain
or seize products, enjoin future violations, or assess civil and/or criminal
penalties against the Company, its officers or employees. Any action by the FDA
could result in disruption of the Company's operations for an undetermined time.

      In addition to the foregoing, numerous other federal and state agencies,
such as environmental, fire hazard control, working condition and other similar
regulators, have jurisdiction to take actions that could have a materially
adverse effect upon the Company's ability to do business. In addition, expansion
of the Company's operations into foreign markets will require the Company to
obtain additional approvals, permits or licenses and comply with additional
regulatory schemes to those of the United States. Amendments to existing
statutes and regulations, adoption of new statutes and regulations and expansion
of the Company's business could require the Company to alter methods of
operations at costs that could be substantial, which could have an adverse
effect on the Company. There can be no assurance that the Company will be able,
for financial or other reasons, to comply with applicable laws and regulations
and approval, permit or license requirements. Currently, the Company believes it
is in compliance with all applicable statutes and regulations governing its
operations and business as currently conducted, including, without limitation,
those in respect of the "SplatrFree(TM)" prophy angles and "The
Wand(TM)",Wand(R)", and the Company has all necessary approvals, permits and
licenses that are applicable to its business, operations and products and
services.

Product Liability

      Failure to use any of the Company's products in accordance with
recommended operating procedures could potentially result in subjecting users to
health hazards or injury. Failures of the Company's products to function
properly could subject the Company to claims of liability. The Company maintains
liability insurance in the aggregate amount of $2,000,000 with a per-occurrence
limit of $1,000,000 and a $10,000,000 umbrella policy which the Company believes
to be adequate. Although no claims have been made against the Company or any of
the customers using its products, there can be no assurance that such claims
will not arise in the future or that the insurance coverage will be sufficient
to pay such claims. A partially or completely uninsured claim, if successful and
of significant magnitude, could have a material adverse effect on the Company.

Research and Development Activities

      During the 1999, and 1998 fiscal years, the Company expensed $455,332 and
$436,024, respectively, on research and development activities.

Employees

      The Company had 24 full-time including three executive officers and 3
part-time employees at December 31, 1999. The Company also uses the services of
certain outside consultants for marketing and other activities.

Certain Risk Factors That May Affect Growth And Profitability

      The following factors may affect the growth and profitability of the
Company and should be considered by any prospective purchaser of the Company's
securities:

      History of Losses; Accumulated Deficit. Our operations commenced in
November 1995, when we acquired a 65% interest in Spintech. For the fiscal years
ending December 31, 1995, 1996 and 1997 we had limited revenues. For the fiscal
years ended December 31, 1998 and 1999 our revenues were approximately $8.8
million and $2.9 million, respectively. In addition, we have had losses for each
of the years ended December 31,


                                       11
<PAGE>

1995, 1996, 1997, 1998 and 1999 including a loss of approximately $7.0 million
for 1999. At December 31, 1999, we had an accumulated deficit of approximately
$27.8 million. We cannot assure you we will be able to generate operating
profits and resultant cash flow sufficient to fund our operations in the future.

      Need for Greater Market Acceptance of "The Wand(R)". As with any new
technology, there is substantial risk that the marketplace will not accept the
potential benefits of such technology or be willing to pay for any cost
differential with the existing technologies. Market acceptance of "The Wand(R)"
depends, in large part, upon our ability to educate potential customers of the
distinctive characteristics and benefits of The Wand(R) and will require
substantial marketing efforts and expense. More than 10,000 Wand units were sold
in aggregate in the U.S. and Canada over the past two years. The 1,250,000 in
disposable handpiece sales for 1999 reflect a low level of usage of The Wand(R).
However, since November 1999 through the present, the Company has experienced
increased disposable handpiece sales in the U.S. If Wand sales and rates of
usage of our products not continue to improve, we may be forced to curtail
marketing efforts and rely on the gradual build-up of demand as a result of
increasing placement of units in dental schools and from growing awareness of
the benefits of The Wand(R) technology as a result of additional clinical
studies. We cannot assure that our current or proposed products will be accepted
by the end users or that any of the current or proposed products will be able to
compete effectively against current and alternative products.

      Limited Financial Resources; Need for Additional Financing. Our capital
requirements have been and will continue to be significant though we believe
after giving effect to the February 2000 private placement that we have
sufficient working capital for the next 12 months. However, if we have
underestimated our operating expenses or our expected revenue, we will be
required to borrow funds or sell equity securities, or curtail or reduce our
activities. As of February 1, 2000 we concluded a $1,000,000 private placement
of secured ten percent notes and warrants for 142,857 shares exercisable at
prices ranging from $1.75 to $7.00 per share. We have no current arrangements
for future additional financing. We cannot assure you any sources of additional
financing will be available on acceptable terms, or at all. To the extent that
any future financing involves the sale of our equity securities, the ownership
interest of our-stockholders could be substantially diluted.

      Highly Competitive Industry; Technological and Product Obsolescence. We
face intense competition from many companies in the medical and dental device
industry, including well-established academic institutions, possessing
substantially greater financial, marketing, personnel, and other resources. Most
of our competitors have established reputations, stemming from their success in
the development, sale, and service of competing dental products. Further, rapid
technological change and research may affect our product. Current or new
competitors could, at any time, introduce new or enhanced products with features
that render our products less marketable, or even obsolete. Therefore, we must
devote substantial efforts and financial resources to enhance our existing
products, to bring our products to market quickly, and to develop new products
for related markets. In addition, our ability to compete successfully, require
that we establish an effective distribution network. Several regulatory
authorities must approve our products before they may be marketed. We cannot
assure you that we can compete successfully, that our competitors will not
develop technologies or products that render our products less marketable or
obsolete, or that we will be able to successfully enhance our existing products,
effectively develop new products, or obtain required regulatory approval for
those products.

      Limited Distribution; Need to Broaden Distribution Channels. Our future
revenues depends on our ability to successfully market and distribute The
Wand(R). During 1999, we relied, primarily, on independent dental distributors
to sell The Wand(R) domestically and internationally. In January 2000, we
entered into an agreement to terminate our existing international distribution
agreement and commenced new international distribution agreement giving our
products entry into Japan, Great Britain, Germany, Israel, South Africa,
Scandinavia, while retaining our presence in China and Taiwan. Domestically, our
sales force' efforts in marketing The Wand(R) continue to grow. It should be
noted, that further increase to the size of the sales force will carry with it a
concomitant increase in up front expenses.


                                       12

      Patent and Intellectual Property Protection. We hold U.S. patents
applicable to the "The Wand(R)" and we have applied for certain improvement
patents on The Wand(R) as well as the "SplatrFree(TM)" prophy angle. We rely on
a combination of patent, trade secret, and trademark laws and employee and
third-party nondisclosure agreements to protect our intellectual property
rights. Despite the precautions we have taken to protect our products,
unauthorized parties may attempt to reverse engineer, copy, or obtain and use
its products and other information we regard as proprietary. We may have to
initiate lawsuits to protect our intellectual property rights. Such lawsuits are
costly and divert management's time and effort away from our business with no
guarantee of success. Our failure to protect our proprietary rights, and the
expense of doing so, could have a material adverse effect on our operating
results and financial condition. Although we have not received any claims of
infringement, it is possible that our products may infringe on existing or
future patents or proprietary rights of others. If that happens we may have to
modify our processes or to obtain a license. We cannot assure you that we will
be able to do so in a timely manner, upon acceptable terms and conditions, or at
all.

      Dependence on Manufacturers. We have informal arrangements with certain
manufacturers with respect to the manufacture of our products. Termination of
the manufacturing relationship with any of these manufacturers could
significantly and adversely affect our ability to produce and sell our products.
Though alternate sources of supply exist and new manufacturing relationships
could be established, we would need to recover our existing tools or have new
tools produced. Establishing of new manufacturing relationships could involve
significant expense and delay. Any curtailment or interruptions of the supply,
whether or not as a result or termination of the relationship, would adversely
affect us.

      Product Liability. We could be subject to claims for personal injury from
the use of our dental and medical products. We have liability insurance in the
aggregate amount of $2,000,000 with a per-occurrence limit of $1,000,000 which
we believe is adequate, although we cannot assure you that the insurance
coverage will be sufficient to pay such claims should they be made. A partially
or completely uninsured claim, if successful and of significant magnitude, could
have a material adverse effect on us.

      Reliance Upon Management. We depend on the personal efforts and abilities
of Leonard Osser, our Chairman and Chief Executive Officer. While we have a key
man life insurance policy in the amount of $3,000,000 on the life of Mr. Osser
any loss of his services could have a materially adverse effect.

      Litigation; Change in Officers. On April 10, 1997, the Board of Directors
of Spintech terminated the employment of Dr. Ronald Spinello as its Chairman and
Director of Research. The action by the Board followed the bringing by Milestone
and Spintech of legal action against Dr. Spinello in which they sought, among
other things, a declaratory judgment that Dr. Spinello has no personal rights to
certain technology developed while he was employed as Director of Research of
Spintech relating to the design and production of ancillary components of "The
Wand(R)" and a declaratory judgment that they had not breached Dr. Spinello's
employment agreement. Milestone, as principal stockholder of Spintech, also
removed Dr. Spinello and Glenn Spinello as directors of Spintech. In February,
2000 we entered into an agreement with Dr. Spinello favorably resolving all
disputes. Pursuant to that agreement, Dr. Spinello assigned to us any right
which he has to technology relating to The Wand(R) developed while Dr. Spinello
was employed at Spintech. Dr. Spinello also agreed to cooperate in filing and to
assign to us all future patent applications covering that technology. As part of
the settlement, Dr. Spinello received $25,000 and 80,000 of our shares.

      A Class Action lawsuit is pending against us seeking damages in an amount
that may substantially exceed our insurance coverage. Further, although we
believe we have meritorious defenses, the defense of the action could divert
management's attention from operation of the business.


                                       13
<PAGE>

      No Dividends. We have never paid a cash dividend on our Common Stock.
Payment of dividends on our Common Stock is within the discretion of the Board
of Directors and will depend upon our earnings, capital requirements and
financial condition, and other relevant factors. We do not currently intend to
declare any dividends on our Common Stock in the foreseeable future.

      Control by Certain Persons. Our current officers and directors own
approximately 23% of the currently outstanding shares of Common Stock.
Accordingly, by reason of their stockholdings, and their control of the means
for soliciting stockholder votes, the officers and directors will be able to
exercise control and, in all likelihood, will be able to continue to elect all
directors.

      Limitation of Director Liability. Our Certificate of Incorporation
provides that our directors are not personally liable to us or any of our
stockholders for monetary damages for breach of the fiduciary duty of care as a
director, including breaches which constitute gross negligence, subject to
certain limitations imposed by the Delaware General Corporation Law. Thus, under
certain circumstances, neither we nor our stockholders can recover damages even
if directors take actions which harm us.

      Government Regulation and FDA Clearance. The manufacture and sale of the
Company's "SplatrFree(TM)" prophy angles and "The Wand(R)", are subject to
extensive regulation by the FDA pursuant to the Federal Food, Drug, and Cosmetic
Act ("FDC Act"), and by other federal, state and foreign authorities. Under the
FDC Act, these medical devices must receive FDA clearance before they can be
commercially marketed in the United States. Some products must undergo rigorous
pre-clinical and clinical testing and an extensive FDA approval process before
they can be marketed. These processes can take a number of years and require the
expenditure of substantial resources. The time required for completing such
testing and obtaining such approvals is uncertain, and FDA clearance may never
be obtained. Delays or rejections may be based upon changes in FDA policy during
the period of product development and FDA regulatory review of each submitted
application. Similar delays may also be encountered in other countries. While
the "SplatrFree(TM)" prophy angle and "The Wand(R)" have received FDA marketing
clearance there can be no assurance that all of our products under development
will obtain the required regulatory clearance on a timely basis, or at all. If
regulatory clearance of a product is granted, such clearance may impose
limitations on the indicated uses for which the product may be marketed. In
addition, modifications may be made to our products to incorporate and enhance
their functionality and performance based upon new data and design review. There
can be no assurance that the FDA will not request additional information
relating to product improvements, that any such improvements would not require
further regulatory review thereby delaying the testing, approval and
commercialization of the our products or that ultimately any such improvements
will receive FDA clearance. FDA regulations also require manufacturers of
medical devices to adhere to certain "Good Manufacturing Practices" ("GMP"),
which include testing, design, quality control and documentation procedures.
Compliance with applicable regulatory requirements is subject to continual
review and will be monitored through periodic inspections by the FDA. Later
discovery of previously unknown problems with a product, manufacturer, or
facility may result in restrictions on such product or manufacturer, including
fines, delays or suspensions of regulatory clearances, seizures or recalls of
products, operating restrictions and criminal prosecution and could have a
material adverse effect on us.

      Restricted Securities; Possible Volatility of Market Price. Shares of our
Common Stock are currently traded on The American Stock Exchange. From time to
time the market prices of dental and medical product companies have been
affected by various factors, including adverse publicity. We cannot assure you
that the market price of our Common Stock will not be volatile as a result of
factors such as our financial results, possible adverse publicity resulting from
any infractions of governmental regulations and various other factors affecting
dental and medical product companies or the market generally. In recent years
the stock market has experienced wide price fluctuations not necessarily related
to the operating performance of such companies.

      Effect of Outstanding Warrants and Options. We currently have outstanding
options and warrants to purchase 1,270,857 shares of our Common Stock at prices
ranging from $1.00 to $23.00 per share. Holders of these warrants and options
are given the opportunity to profit from a rise in the market price of our
Common


                                       14
<PAGE>

Stock and are likely to exercise their securities at a time when we would be
able to obtain additional equity capital on more favorable terms. Thus, the
terms upon which we will be able to obtain additional equity capital may be
adversely affected since the holders of outstanding options and warrants can be
expected to exercise them at a time when we would, in all likelihood, be able to
obtain any needed capital on terms more favorable to us than the exercise terms
provided by such outstanding securities. We have granted registration rights
with respect to our shares of our Common Stock covered by the warrants.

Item 2.  Description of Property

      On March 20, 1997 Milestone opened new corporate headquarters and
administrative offices occupying approximately 2,693 square feet at 220 South
Orange Avenue, Livingston Corporate Park, Livingston, New Jersey. The Company
occupies this space under a five (5) year and one (1) month lease at a cost the
Company believes to be competitive. Spintech's accounting functions were moved
to the new corporate headquarters. Spintech's operational functions are located
at and consolidated with the other operations in Deerfield, Illinois.

      In October 1999, the Company consolidated its operations in Deerfield,
Illinois, moving from two facilities to a single facility (approximately 5,470
square feet) in the same business complex. A five-year lease was signed. The
facility serves as distribution center for the Company's products and the
telemarketing office.

Item 3. Legal Proceedings

      Spinello Lawsuits

      On March 26, 1997, Milestone and Spintech commenced legal action in the
United States District Court of New Jersey against Ronald Spinello, DDS, former
Chairman and Director of Research of Spintech. In the complaint, plaintiffs
sought recovery of compensatory and punitive damages for extortion and tortuous
interference with existing and prospective contract and business relationships,
a declaratory judgment that Dr. Spinello has no personal rights to certain
technology developed while he was employed as Director of Research of Spintech
relating to the design and production of ancillary components of its computer
controlled local anesthetic delivery system, a declaratory judgment that
plaintiffs have not breached Dr. Spinello's employment agreement or the
agreement for the initial purchase by Milestone of a 65% equity interest in
Spintech and injunctive relief. On May 21, 1997, Dr. Spinello filed an answer
and counterclaim.

      As a result of various pretrial motions, the only claims remaining in the
litigation with Dr. Spinello were Milestone's claims against Dr. Spinello and
Dr. Spinello's counterclaim for unpaid salary for the period subsequent to his
alleged wrongful termination, and a portion of his indemnification claim against
Spintech.

      In January 2000, prior to trial, the Company agreed to settle with Dr.
Spinello, the counterclaims asserted against Dr. Spinello and the claims
asserted by Glenn Spinello. Various stipulations incorporating that settlement
were executed in February 2000. Under the agreement, Dr. Spinello has assigned
to Milestone any rights which he has to technology relating to "The Wand(R)"
handpiece or technology developed while he was employed at Spintech and has
agreed to cooperate in filing and to assign to Milestone any future patent
applications covering that technology. Dr. Spinello and Glenn Spinello each also
agreed to convey to Milestone all of his equity interests in Spintech. In return
for the assignment of technology, the conveyance of Spintech equity and the
resolution of all disputes between the parties, including the discontinuance
with prejudice of pending legal actions, Milestone has paid $25,000 to Dr.
Spinello and has agreed to issue to him a number of shares of Common Stock equal
to the greater of 80,000 shares or shares with a market value of $80,000 and to
issue to Glenn Spinello 8,000 shares.


                                       15

      Class Action Lawsuit

      In 1998, several class action lawsuits were commenced against the Company,
certain present and former executive officers, one outside director and
consultants in the United States District Court for the District of New Jersey.
The District Judge before whom the cases are pending has entered an order
consolidating all of the class actions into one consolidated action. The
Complaints contain generally overlapping and similar allegations of violations
of the Securities Exchange Act of 1934, including allegations that the Company
and certain of the other defendants violated the Act by issuing false and
misleading financial statements and disseminating misleading statements about,
among other things, the demand for the Company's principal product, its expected
sales growth, the acceptance of that product by dental professionals, shipments
during certain time periods and misrepresentations as to third-party evaluations
of the efficacy of the product through failure to disclose the issuance of stock
options to certain consultants. On October 22, 1998, the District Judge entered
an order appointing lead plaintiff to represent the interests of all class
members. On March 28, 1999, the District Judge appointed lead counsel to
represent the class. On April 28, 1999, the class filed a Consolidated and
Amended Class Action Complaint, naming as defendants the Company and three
present and former executive officers and directors. The Consolidated Complaint
alleges that the Company issued false and misleading statements concerning,
among other things, certain studies and reports on the Company's products, the
Company's backlog and the amount of reserve taken for returns. Milestone
believes that the material allegations of the Consolidated Complaint does not
state a cause of action under the Federal Securities Law and on May 21, 1999
served a motion to dismiss the Consolidated Complaint for failure to state a
claim. The class has responded to the motion and the Company filed a reply. The
Motion was submitted to the Court in September 1999, but no decision has yet
been rendered. Instead, on March 1, 2000, the Court held oral argument on the
Motion to Dismiss, at the end of which the court requested supplemental
memoranda of law on one issue. The Supplemental Memoranda Of Law were filed on
March 16 and 22, 2000. If the Motion to Dismiss is not granted, the Company
believes that the allegations contained in the Class Action Complaint are
without merit and it intends to vigorously defend the action. Specifically,
Milestone believes that its financial statements presented fairly its results of
operations, that the information which it has publicly disclosed did not contain
any material misstatements or misrepresentations and that stock options issued
to persons who published research reports were issued for other services for the
Company, principally service as spokespersons and demonstrators of the Company's
product. Further, the Company continues to believe that The Wand(R) embodies
superior technology, is a major advance in dentistry and may ultimately become
the accepted method for delivering local dental anesthesia.

      Derivative Action Lawsuit

      In February 1999, a purported owner of Milestone stock, commenced a
derivative action on behalf of the Company, in the Court of Chancery of the
State of Delaware in Newcastle County, against certain present and former
executive officers and directors. In the action, plaintiff alleges that, based
on the same facts as the class actions described above, the defendants engaged
in violations of the securities laws, committed fraud and securities fraud,
wasted corporate assets and damaged the Company's reputation. As a derivative
action, even if the plaintiff is successful, any award, after deduction of
plaintiff's costs and disbursements, would be payable to the Company.
Nevertheless, Milestone believes that the material allegations of the complaint
lack merit and intends to provide a legal defense for its present and former
officers and directors in accordance with the indemnification provisions of its
Certificate of Incorporation. Because the allegations of the Derivative
Complaint are so closely tied to the allegations of the Class Complaint, the
Derivative Plaintiff's counsel has agreed with the Company that no response to
the Derivative Complaint is due until 60 days after the Court in the Class
Action decides the motion to dismiss.


                                       16

      Insurance Broker and Carrier

      In January 1999, the Company filed a complaint against its insurance
broker (Frank Crystal Financial Services) and the two excess insurers [American
Alliance and St. Paul] in the United States District Court for the District of
New Jersey. American Alliance and St. Paul were in dispute with the Company
because they claim that the Company did not timely submit the appropriate
application. As a result, American Alliance refused to issue a policy and St.
Paul, which issued a policy, has refused to cover the class actions described
above. In April 1999, the Company reached a settlement of this action, as a
result of which American Alliance issued the Excess Director's and Officer's
Insurance Policy; the Company agreed that claims arising prior to the date of
the policy were not covered by the policy and the parties reserved all of their
arguments and positions with respect to any other coverage issues including
those that resulted from the Consolidated and Amended Class Action Complaint
referred to above.

      On June 24, 1999 American Alliance filed a complaint in the United States
District Court for the Southern District of New York seeking a declaratory
judgment that it is not liable under its policy for the claim asserted in the
amended class complaint as well as the derivative complaint. The Company intends
to vigorously defend against the American Alliance action and intends to move to
dismiss that action. On July 9, 1999 the Company filed its own declaratory
judgment action against American Alliance and St. Paul in the United States
District Court for the District of New Jersey seeking a declaration that the
claims asserted in the Consolidated Complaint in the Class Action and in the
Derivative Action are covered by the Excess Director's and Officer's Insurance
Policies. On August 4, 1999, the District Judge in New Jersey administratively
terminated the Company's action until the previously filed New York Action was
resolved or dismissed. Thereafter, the Company filed an answer and counterclaim
in the New York Action seeking the same relief as it sought in its complaint in
the New Jersey Action. Both American Alliance and the Company each requested
leave from the Judge in the New York Action to make a motion for summary
judgment and to dismiss the complaint, respectively. Instead, since any decision
on the scope of coverage of the excess policies will, in large part, depend upon
whether the Class Action complaint is dismissed, in whole or in part, the
District Judge in the New York Action decided to hold in abeyance any action on
American Alliance's complaint and Milestone's answer and counterclaim until a
decision is rendered by the District Court in New Jersey in the Class Action.

ITEM 6. Management's Discussion and Analysis of Financial Condition and Results
        of Operation

      1999 was a year of transition for Milestone Scientific. It expanded its
market from the U.S. and Canada to a global market, including Europe, Asia,
Africa and South America. International sales were somewhat limited, pending
establishment of arrangements with local dealers. The need for regulatory
approval in some jurisdictions also limited sales activity, though shortly after
year end the Company received approval to market the Wand in Japan. Also,
Milestone transformed itself from a company which distributed its product
through a dealer network to a company distributing directly to U.S. dentists. As
part of focused efforts on its core products, Milestone terminated its Wisdom
operations.

      Fiscal year ended December 31, 1999 compared to fiscal year ended December
31, 1998

Statement of Operations

Net sales for the year ended December 31, 1999 and December 31, 1998 were
$2,855,463 and $8,804,235 respectively. The $5,948,772 or 68% decrease reflects
a decline in Wand sales volume (including disposable handpieces) partially
offset by a decrease in returns. The sales decline was caused by a decline in
new customer demand for Wand equipment units after the filling of orders for
early adapters during the first six months of 1998 and limited usage of
disposables by purchasers of equipment units. Furthermore, net sales from the
Wisdom product line which was terminated in April, 1999 were $174,086 for the
year ended December 31, 1999 as compared to $1,983,277 for the year ended
December 31, 1998. For the year ended December 31, 1999, approximately $543,000
in revenue or 19% was generated from sales to foreign distributors. In addition,
$499,000 of the $2,312,000 in domestic sales were destined for foreign end
users.

      Cost of sales for the year ended December 31, 1999 as compared to the year
ended December 31, 1998 declined from $10,144,796 to $1,572,319, a $8,572,477
reduction. The reduction is primarily attributable to lower sales volume, a
sharp decline in returns and a decrease in average product costs due to prior
period inventory writedowns.

      Included in the cost of sales for the year ended December 31, 1998 is a
$1,243,986 writedown of the aggregate carrying value of the Wand(R) and the
disposable handpieces inventories and a $1,982,000 writedown in the net book
value of fixed assets. The carrying value of the inventory was reduced to
reflect the inventory value under the market conditions as of December 31, 1998.
The latter reduction includes a $269,000 obsolete equipment writeoff. The
remainder or $1,712,982 is the writedown of new, yet unused semi automation
equipment and molds. The semi automation equipment and molds were purchased for
approximately $2,200,000 in anticipation of the ramp up disposable handpiece
sales which did not materialize.

      For the year ended December 31, 1999, the Company generated a gross profit
of $1,283,144 as compared to a gross loss of $1,340,561 for the year ended
December 31, 1998.

      Selling, general and administrative expenses for the year ended December
31, 1999 and December 31, 1998 were $7,009,543 and $9,336,445 respectively. The
$2,326,902 or 25% decrease is primarily attributable to approximately $1,630,000
aggregate decrease in selling and marketing expenses associated with The
Wand(R), a $270,000 reduction in corporate salaries, a $221,452 decrease in
compensation expense related to 1998 option grants, and a $498,000 reduction in
selling and marketing expenses associated with the Wisdom product line. These
expenses were offset by a $366,000 increase in legal expenses and a $168,000
increase in insurance expenses.

      In April 1999, the Company discontinued its selling effort with regards to
the Wisdom product line excluding Splatrfree(TM) prophy angles. $76,345 in
aggregate costs were incurred in terminating the product line. They included
$19,291 for uncollectible receivables, $15,692 in aggregate termination
compensation and employee benefits, $5,066 for a lease buyout, $18,793 in
previously unamortized acquisition costs and $17,503 to write off


                                       19
<PAGE>

Wisdom inventory currently earmarked for distribution to charities and trade
associations. Furthermore, the termination compensation covered the last Wisdom
employee.

      Research and development expenses for the year ended December 31, 1999 and
December 31, 1998 were $455,332 and $436,024, respectively. The $19,308 increase
is primarily attributable to the cost incurred in developing product
improvements and a medical version of "The Wand(R)".

      Loss from operations for the years ended December 31, 1999 and 1998 were
$6,258,076 and $11,113,030, respectively.

      Net interest income for the years ended December 31, 1999 and 1998 were
$17,014 and $414,676. The $397,662 decrease is primarily attributable to lower
aggregate funds available for investing and additional interest expense
associated with senior convertible notes. Also, as a result of a reduction in
the conversion price for the 3% convertible notes, the Company incurred a non
cash debt conversion expense of $731,250 in 1999.

      The net loss for the year ended December 31, 1999 was $6,972,312 as
compared to net loss of $10,698,354 for the year ended December 31, 1998. The
decrease reflects sharp declines in product returns and in selling general and
administrative expenses, a decrease in the average product cost, and 1998
writedowns in inventory carrying values and in the net book value of production
equipment and molds associated with the Wand(R). This is partially offset by a
decline in Wand(R) sales volume, lower net interest income and a $731,250 debt
conversion expense.

Liquidity and Capital Resources

      At December 31, 1999, the Company's working capital was $1,207,778. It
consisted primarily of inventories, investment in treasury bills and cash and
cash equivalents.

      For the year ended December 31, 1999, the Company decreased cash and cash
equivalents by $73,863, providing $3,161,134 from investing activities and
$2,098,000 from financing activities.

      For the year ended December 31, 1999, the Company's net cash used in
operating activities was $5,332,997. This was primarily attributable to a net
loss of $6,972,312 adjusted for non cash items of $263,950 for amortization,
$468,907 for depreciation, $36,438 for non cash interest and a $731,250 debt
conversion expense; a $133,129 decrease in accounts receivable; a $461,832
increase in inventories; a $65,373 increase in prepaid expenses; an increase in
accrued expenses of $81,151 and a $451,415 increase in accounts payable. The
$133,129 decrease in accounts receivable includes a $291,532 reduction in
accounts receivable associated with the Wisdom product line, partially offset by
a $77, 224 reduction in the allowance for doubtful accounts associated with Wand
customers. Approximately $50,000 of the $79,814 allowance for doubtful accounts
at December 31, 1999 is to fully reserve against outstanding receivables from
the Wisdom product line.

      The $3,161,134 provided by investing activities for the year ended
December 31, 1999 was attributable to the maturing of $7,020,940 in treasury
bills, offset by $3,753,000 in Treasury bill purchases and $106,806 in capital
expenditures. These expenditures covered retooling cost for product
modifications.

      Financing activities provided $2,098,000 for the period. The Company, as
described below, raised $2,000,000 from an institutional private placement and
$250,000 from the sale of similar securities to its Chairman and CEO. Also,
$150,000 was repaid under the Company's line of credit.

      The recoverability of a major portion of the recorded assets of the
Company is dependent upon the continuing operations of the Company, the success
of the Wand product and the Company's ability to obtain necessary financing
through January 1, 2001. As of December 31, 1999, the Company had $242,843 in


                                       20
<PAGE>

aggregate cash and cash equivalents. In addition, as of February 1, 2000, the
Company concluded a $1,000,000 private placement of 10% Senior Subordinated
Note. Also, on April 5, 2000, the chairman of Milestone signed an agreement
which provides the company was a $200,000 line of credit at 9% through February
1, 2001. Payment guarantees on year 2000 sales to certain foreign countries
through two specified distributors; and the option to defer his salary through
January 3, 2001 should the line of credit be insufficient. Management believes
that through the proper utilization of these existing funds, revenues generated
from international distributors and from continued increases in domestic
disposable handpiece sales, the expense reductions achieved through cost
containment programs, and the funds raised from the first quarter 2000 private
placement, it will have sufficient cash to meet its needs over the next twelve
months.

      The Company continues to take steps aimed at growing and strengthening the
end user base thereby gaining greater acceptance of The Wand(R) and translating
to increased revenue through higher disposable handpiece usage. On October 1,
1999, the Company began a new sales initiative, permitting dentists in the
United States to order the Wand(R) directly through Milestone and to avail
themselves of certain quantity discounts when purchasing disposable handpieces
and dental needles. Furthermore, it continues to a) develop its market overseas;
b) visit, obtain feedback and provide further support to current Wand users; c)
provide assistance to dental schools which include The Wand(R) in their
curriculum; d) distribute The Wand(R) technique videos and technical bulletins
to its current users, and e) maintain a well trained service staff.

      Subsequent to year-end, the Company achieved two major objectives. As
mentioned above, it completed a $1,000,000 private placement, issuing 10% Senior
Secured Notes with warrants to purchase 142,857 shares of Milestone Common
Stock. Secondly, it received approval to sell "The Wand(R)" and its disposable
handpiece in Japan. An order of 1,000 units and 150,000 disposable handpieces
was immediately received from its exclusive distributor, Yoshida Dental
Manufacturing Company. As requested, 500 units and 50,000 disposable handpieces
were shipped by March 26, 2000. Since November 1999 and through March 2000 the
Company has experienced monthly growth in domestic handpiece sales. First
quarter 2000, revenues are expected to exceed the prior quarter's revenues by
over 50%. Also, cash receipts through March 26, 2000 were over $1.2 million for
the quarter.

      In August 1999, the Company submitted an application to the FDA to market
for medical use, a similar device to The Wand(R). A working prototype of an
improved device for delivery of multi-volume anesthetic and other medicaments
and with other added features of interest to medical specialists has been
developed and will be submitted to the FDA in the near future.

      Private Placements

      In March 1999, the Company concluded a $2 million institutional private
placement with Cumberland Partners, other investment funds managed by or
affiliated with Cumberland Associates and certain principals of Cumberland
Associates. An additional $250,000 was raised from the Chairman and Chief
Executive Officer of Milestone, on the same terms and conditions. The investors
purchased, at face value, 3% Senior Convertible Notes Due 2003, convertible into
Milestone Common Stock at prices increasing from $2.50 per share in the first
year to $6.00 per share in the fourth year, subject to anti-dilution protection
in the event of stock dividends and certain capital changes. Purchasers of the
Notes were granted rights to participate in certain future security offerings by
Milestone. Subsequent to year end, in February 2000, the holders of the 3%
Convertible Notes agreed to convert all $2,250,000 of such notes into common
stock at an $1.25 per share. Of the 1,800,000 shares which were to be issued,
only the 200,000 shares to Mr. Osser are being held in escrow and pending
shareholder approval.

      As of February 1, 2000, the Company concluded a $1 million institutional
private placement of 10% Senior Secured Promissory Notes due June 30, 2001 and
Warrants to purchase 142,857 shares of Milestone Common Stock with Cumberland
Associates, Strategic Restructuring Partnership L.P., a former principal of
Cumberland


                                       21
<PAGE>

Associates, two officers of the Corporation, an affiliate of one of its
directors and six other individuals. The Notes are secured by all present and
future inventories of Milestone and are prepayable out of a portion of the
proceeds generated by sales of "Wand" units. The Warrants are exercisable at
prices increasing from $1.75 per share in the first year to $7.00 per share in
the fifth year, subject to anti-dilution protection in the event of stock
dividends and certain capital changes. Purchasers of the Warrants were granted
rights to participate in certain future security offerings by Milestone.

Year 2000 Compliance

      The Company experienced no disruption with regards to the year 2000. It
had developed a plan which included the upgrade of its internal information
system and insured that its operating systems were compliant with the
requirements to process transactions in the year 2000. The cost was not
significant for overall compliance. The Company reviewed its own equipment and
determined that the equipment was either Year 2000 compliant or not affected by
the Year 2000 issues. Also, the Company contacted its vendors, on whom it
relies, and they too were Year 2000 complaint.

Subsequent Events

      International Distribution Arrangement

      In January 2000, the Company entered into an agreement with AFP to
terminate international distribution of "The Wand(R)" through AFP by June 30,
2000.

      The agreement provides for a phased termination during which Milestone
will immediately begin to fill handpiece requirements of all existing and new
foreign dealers throughout the world and will directly distribute "Wand(R)"
units to dealers in Japan, Great Britain, Germany, Israel, South Africa,
Scandinavia and certain other countries. Milestone currently serves dealers in
China, and Taiwan. In addition, the Company will assume responsibility for
distribution to dealers in Central and South America in April 2000 and for
dealers throughout the rest of the world after June 30, 2000.

      The change in Milestone's international distribution arrangements, was
made to bring Milestone one step closer to the end user, allowing it to better
serve the individual practitioner. It should provide more pricing flexibility
and allow cost reductions to Milestone's end users.

      Approval for the Sale of "The Wand(R)" System in Japan

      In February 2000, the Company received approval to sell "The Wand(R)" and
disposable handpiece in Japan. Following the approval, Milestone's exclusive
Japanese distributor, The Yoshida Dental Manufacturing Co., placed an initial
order for 1,000 system kits and 150,000 disposable handpieces. Japan is the
world's second largest dental market and Yoshida is one of Japan's largest
wholesale dental equipment and product distributors. Yoshida has 400 sales
representatives staffing offices located in 44 major cities and its distribution
network has agreements with approximately 25% of the more than 600 dental
dealers in Japan.

Section 16(a) Beneficial Ownership Reporting Compliance

      Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's officers and directors, and persons who own more than ten percent
(10%) of a registered class of the Company's equity securities to file reports
of ownership and changes in ownership with the Securities and Exchange
Commission ("SEC"). Officers, directors and greater than ten percent (10%)
stockholders are required by SEC regulations to furnish the Company with copies
of all Section 16(a) forms they file.

      To the best of the Company's knowledge, based solely on review of the
copies of such forms furnished to the Company, or written representations that
no other forms were required, the Company believes that all Section 16(a) filing
requirements applicable to its officers, directors and greater than ten percent
(10%) shareholders were complied with during 1999, with the exception of the
following individuals with late Form 4 filings reporting changes in beneficial

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors
    Milestone Scientific Inc.

We have audited the accompanying consolidated balance sheet of Milestone
Scientific Inc. and Subsidiaries as of December 31, 1999 and 1998 and the
related consolidated statements of operations, changes in stockholders' equity,
and cash flows for each of the two years in the period ended December 31, 1999.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Milestone
Scientific Inc. and Subsidiaries as of December 31, 1999 and 1998, and the
consolidated results of their operations and their consolidated cash flows for
each of the two years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States.

Supplemental schedule of noncash investing and financing activities:

In 1998, 7,425 warrants were issued to a former board member for services
rendered as such, which were also exercised during 1998 in a cashless
conversion. Accordingly, the Company recognized a total noncash charge of
$95,000 as compensation expense for the fair value of the warrants issued and
exercised.

In September 1999, in making the first semi annual interest payment on the
Senior Convertible Notes and in accordance with the terms of the note
agreements, the Company elected to issue 47,016 shares of Milestone Common Stock
in lieu of cash of $36,438.

The accompanying notes are an integral part of these statements.

                          NOTES TO FINANCIAL STATEMENTS

                           December 31, 1999 and 1998

NOTE A - BASIS OF PRESENTATION

      The accompanying financial statements have been prepared in conformity
      with generally accepted accounting principles, which contemplate
      continuation of the Company as a going concern. However, subsequent to its
      first fiscal quarter in 1998, the Company has incurred substantial losses
      from operations. In addition, the Company has used, rather than provided,
      cash in its operations during the years ended December 31, 1999 and 1998.

      In view of the matters described in the preceding paragraph,
      recoverability of a major portion of the recorded asset amounts shown in
      the accompanying balance sheet is dependent upon continued operations of
      the Company, which in turn is dependent upon the success of the Company's
      Wand(R) product and the Company's ability to obtain necessary financing
      through January 1, 2001. The financial statements do not include any
      adjustments relating to the recoverability and classification of recorded
      asset amounts or amounts and classification of liabilities that might be
      necessary should the Company be unable to continue in existence.

      Based on management's belief that The Wand(R), is a major advance in
      dentistry and may ultimately become the accepted method for delivering
      local dental anesthesia, the Company continues to take steps aimed at
      growing and strengthening the end user base thereby gaining greater
      acceptance of The Wand(R) and translating to increased revenue through
      higher disposable handpiece usage. On October 1, 1999, the Company began a
      new sales initiative, permitting dentists in the United States to order
      the Wand(R) directly through Milestone and to avail themselves of certain
      quantity discounts when purchasing disposable handpieces and dental
      needles. Furthermore, it continues to a) develop its market overseas; b)
      visit, obtain feedback and provide further support to current Wand(R)
      users; c) provide assistance to dental schools which include The Wand(R)
      in their curriculum; d) distribute The Wand(R) technique videos and
      technical bulletins to its current users, and e) maintain a well trained
      service staff.

      As of December 31, 1999, the Company had $242,843 in aggregate cash and
      cash equivalents. In addition, as of February 1, 2000, the Company
      concluded a $1,000,000 private placement of 10% Senior Subordinated Note
      (See Note O). Management believes that through the proper utilization of
      these existing funds, revenues generated from international distributors
      and from continued increases in domestic disposable handpiece sales, the
      expense reductions achieved through cost containment programs, and the
      funds raised from the first quarter 2000 private placement, it will have
      sufficient cash to meet its needs over the next twelve months.

                           December 31, 1999 and 1998

NOTE A (continued)

      In addition, on April 5, 2000 Leonard Osser, the Chairman and CEO of the
      Company, signed an agreement which provides the Company through December
      31, 2000 with the following: 1) a $200,000 line of credit with a maturity
      of February 1, 2001 and a 9% annual interest rate; 2) payment guarantees
      on year 2000 sales to certain foreign countries through two specified
      distributors; and 3) the option, should the line of credit be
      insufficient, to defer payment of his full salary until January 3, 2001.
      Furthermore, Mr. Osser and one other participant in the February 2000
      private placement agreed to amend the Company's promissory note agreement
      so as to defer all payments including interest until January 3, 2001.
      These notes comprised $300,000 of the $1,000,000 private placement.

NOTE B - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Organization of Business

      Milestone Scientific Inc. (formerly U.S. Opportunity Search, Inc.) (the
      "Company") was incorporated in the State of Delaware in August 1989. The
      Company develops, manufactures, markets and sells equipment and related
      disposable or consumable items and other products for use primarily by
      dental practitioners, throughout the world.

      In November 1995, the Company purchased 65% of the common stock of
      Spintech, Inc. ("Spintech"). (See Note D.) Spintech was founded to perform
      research and to develop patented products for use by health care
      providers. Spintech has had only limited sales of its products. These
      limited sales provide no assurance that Spintech will be able to
      successfully market these products and that demand will be at the levels
      at which Spintech can operate profitably.

      In March 1996, the Company, together with one of its officers, founded
      Princeton PMC, Inc. ("Princeton PMC") as a marketing company. The Company
      acquired the remaining outstanding shares of Princeton PMC, Inc. common
      stock owned by the officer in November 1996, making Princeton PMC, Inc. a
      wholly-owned subsidiary. In December 1996, the Company acquired Sagacity
      I, Inc. ("Sagacity"), doing business in the United States as the Wisdom
      Toothbrush Co. ("Wisdom"), and obtained United States distribution rights
      to the Wisdom line of toothbrushes and prophylaxis products (See Note D).
      Wisdom had an exclusive three-year distributor agreement in the United
      States, Canada and other areas with Wisdom Toothbrushes Limited ("Wisdom
      UK"). This agreement was mutually terminated in March 1999.

                    NOTES TO FINANCIAL STATEMENTS (continued)

                           December 31, 1999 and 1998

NOTE B (continued)

      In December 1997, in addition to doing business as Wisdom, Sagacity
      commenced doing business in the United States as Milestone Scientific,
      Inc. ("Milestone").

      A summary of the significant accounting policies consistently applied in
      the preparation of the accompanying financial statements follows:

      1.    Principles of Consolidation

            The consolidated financial statements include the accounts of the
            Company and all of its wholly-owned and majority-owned subsidiaries.
            All material intercompany accounts and transactions have been
            eliminated.

      2.    Cash and Cash Equivalents

            For purposes of the statements of cash flows, the Company considers
            all highly liquid investments purchased with a maturity of three
            months or less to be cash equivalents.

      3.    Investments - Treasury Bills

            The Company carries its Treasury Bills at cost plus accrued
            interest, which approximates fair value.

      4.    Inventories

            Inventories are valued at the lower of cost or market with cost
            being determined by the first-in, first-out ("FIFO") method.
            Inventories principally consist of finished goods.

      5.    Property and Equipment

            Property and equipment are stated at cost and depreciated using
            straight-line and accelerated methods over the estimated useful
            lives of the assets. The estimated useful lives to be used to
            determine depreciation are as follows:

                    Furniture and fixtures             7 years
                    Office equipment                   5 years
                    Trade show displays                5 years
                    Tooling equipment              5 - 7 years
                    Computer and software              3 years

                           December 31, 1999 and 1998

NOTE B (continued)

      6.    Patents

            The excess of the Company's cost over the tangible net assets of
            Spintech has been allocated to patents and is being amortized over a
            ten-year period using the straight-line method. The recoverability
            of the carrying values of the patents are evaluated on a recurring
            basis.

      7.    Revenue Recognition

            Revenue is recognized when title passes at the time of shipment.

      8.    Research and Development

            Research and development costs are expensed as incurred.

      9.    Loss Per Common Share

            Loss per common share is computed based on the weighted average
            number of shares of common stock outstanding. The effect on the loss
            per share of warrants and options outstanding is antidilutive and
            has not been included in the calculation of weighted average shares
            outstanding. (See Note F for additional information.)

      10.   Use of Estimates in Financial Statements

            In preparing financial statements in conformity with generally
            accepted accounting principles, management makes estimates and
            assumptions that affect the reported amounts of assets and
            liabilities and disclosures of contingent assets and liabilities at
            the date of the financial statements, as well as the reported
            amounts of revenues and expenses during the reporting period. Actual
            results could differ from those estimates.

NOTE D - ACQUISITIONS

      Wisdom

      In December 1996, the Company completed the purchase of Wisdom's
      outstanding stock by issuing 23,250 shares of its common stock valued at
      $110,437. The acquisition has been recorded using the purchase method of
      accounting. The cost was less than the subsidiary's net assets at the date
      of acquisition. The excess of net assets over cost has been applied to
      reduce the amounts assigned to noncurrent assets of the subsidiary. The
      operating results of Wisdom have been included in the Company's
      consolidated financial statements since the date of acquisition.

      In April 1999, the Company discontinued its selling effort with regards to
      the Wisdom product line excluding SplatrFree(TM) prophy angles. The
      discontinued products generated net sales of $174,086 and an operating
      loss of $52,911 for the year ended December 31, 1999. For the year ended
      December 31, 1998, these products generated $1,983,277 in net sales and
      operating income of $70,329. In terminating the product line the Company
      incurred $76,345 of expenses, including $19,291 for uncollectible
      receivables, $15,692 in aggregate termination compensation and employee
      benefits, $5,066 for a lease buyout, $18,793 in previously unamortized
      acquisition costs and $17,503 to write off inventory.

      The Company had a line of credit which had originally been secured by the
      assets associated with the Wisdom product line. In June 1999, the Company
      obtained a thirty-day extension of its $250,000 line of credit with some
      temporary modifications including a line reduction. On July 26, 1999, the
      Company notified its lender that the Company would no longer be utilizing
      the line and remitted the outstanding balance of $50,000.

      Spintech

      In November 1995, the Company completed the purchase of 65% of Spintech's
      outstanding stock on a fully diluted basis for $2,700,000. The Company
      paid $2,026,495, which represents the $2,700,000 less amounts advanced to
      Spintech amounting to $632,500 plus interest of $41,005. The acquisition
      has been recorded using the purchase method of accounting. The excess of
      the aggregate purchase price over the net tangible assets acquired was
      allocated to patents and is being amortized over ten years. The operating
      losses of Spintech have been included in the Company's consolidated
      financial statements since the date of acquisition. Because of recurring
      losses. the minority interest has been valued at zero for the years ended
      December 31, 1998 and 1999.

                    NOTES TO FINANCIAL STATEMENTS (continued)

                           December 31, 1999 and 1998

NOTE D (continued)

      On several occasions, during 1997, the Company offered, to those minority
      shareholders of Spintech who are accredited investors, the opportunity to
      exchange their Spintech shares for Milestone. The conversion offer ranged
      from 6.1 to 24.43 shares of Milestone for 1 share of Spintech. These
      offers were for restricted shares, and 1,017 shares of Spintech were
      converted.

      Also, the Company holds a series of annual options to purchase, for a
      nominal amount, an additional 3% of Spintech's outstanding shares
      following each of the first five fiscal years commencing after the closing
      of the stock purchase (or an aggregate of 15% of such shares if all of the
      options are exercised). Each option is exercisable only if Spintech does
      not achieve a specified pretax profit target as defined in the applicable
      fiscal year. As a result of Spintech not achieving the specified pretax
      profit, the Company exercised its option in 1997, 1998 and 1999. The
      option exercised in 1999 increased the Company's ownership in Spintech to
      75.9%. Milestone's ownership was 73.4% as of December 31, 1998. The
      Company's ownership increased to 79.3% on February 10, 2000 when Ronald
      and Glen Spinello surrendered their shares as part of the settlement
      agreementThe value of the converted shares and associated offering costs
      are reflected in the accompanying balance sheet as patents.

      Subsequent to year end and as part of the resolution of the disputes
      between the Company and Dr. Ronald Spinello along with Glenn Spinello (See
      Note O), the Spinello's agreed to convey all of their equity interests in
      Spintech. The 5,025 shares conveyed increased Milestone's ownership in
      Spintech to 79.3%.

      In addition, the Company provides advances to Spintech. These advances are
      due on demand with interest at 8%. The balance of the advance account
      including interest as of December 31, 1998 and 1999 were $11,827,924 and
      $13,378,266, respectively.

NOTE E - 3% Convertible Notes And Other Borrowing

      3% Convertible Notes

      In March 1999, the Company concluded a $2 million institutional private
      placement with Cumberland Partners, other investment funds managed by or
      affiliated with Cumberland Associates and certain principals of Cumberland
      Associates. An additional $250,000 was raised from the Chairman and Chief
      Executive Officer of Milestone, on the same terms and conditions. The
      investors purchased, at face value, 3% Senior Convertible Notes Due 2003,
      convertible into Milestone Common Stock at prices increasing from $2.50
      per share in the first year to $6.00 per share in the fourth year, subject
      to anti-dilution protection in the event of stock dividends and certain


                                      F-13

      capital changes. Purchasers of the Notes were granted rights to
      participate in certain future security offerings by Milestone.

NOTE E - (continued)

      In December 1999, the holders of the 3% Convertible Notes agreed, and in
      February 2000 formalized the agreement to convert all $2,250,000 of such
      notes into common stock at a modified price of $1.25 per share. Of the
      1,800,000 shares which were to be issued, only the 200,000 shares to Mr.
      Osser are being held in escrow and pending shareholder approval.

      Since the scheduled conversion price was $2.50 per share, the Company
      recognized a non cash debt conversion expense of $731,250 in 1999.

      In September 1999, the Company issued 47,016 shares of Milestone Common
      Stock in lieu of cash of $36,438 in making the first semi annual interest
      payment, on the Senior Convertible Notes as permitted by the terms of the
      purchase agreement.

      Other Borrowings

      During the first quarter of 2000, the Company completed a $1,000,000
      private placement of 10% Senior Secured Promissory Notes due June 30, 2001
      and Warrants to purchase 142,857 shares of Milestone Common Stock (See
      Note O).

NOTE F - STOCKHOLDERS' EQUITY

      In March 1997, the Company sold, in a private placement, an aggregate of
      852,262 units at $4.72 per unit for net cash proceeds of $3,309,265, less
      noncash costs for shares and warrants issued in connection with the
      private placement of $1,316,350 for a net amount of $1,992,915. Each unit
      consisted of one share of common stock and one common stock purchase
      warrant. Each warrant entitles the holder to purchase one share of common
      stock for three years from the closing of the offering at an exercise
      price of $4.72 per share. In addition, the placement agent received
      warrants to purchase 85,226 units at $4.72 per unit. The 207,231 warrants
      which were outstanding as of December 31, 1999, expired on March 13, 2000.

      NOTE F (continued)

      During 1996 and 1997, the Company granted stock options to a director and
      various consultants to purchase 35,000 and 164,000 shares of common stock,
      respectively, at prices ranging from $5.125 to $6.50 per share. The
      options expire in three to five years depending on the option, vest over
      two to three years and contain certain anti-dilution provisions. All
      options were unexercised at December 31, 1999.

      During 1996, the Company issued 60,000 shares to a consultant for services
      provided to the Company. The agreement stipulated that if the consultant
      is permitted to sell and does sell the shares issued to him and realizes
      from such sale net proceeds of less than $5 per share, the Company shall
      supplement such proceeds up to $5 per share, provided the Company's total
      obligation shall not exceed $105,000. During 1999, this agreement was
      amended so as to reduce the numbers of shares covered from 60,000 to
      20,000, limit the Company's obligation to $100,000 and to establish a
      specified four month period during 1999 when applicable. Subsequently, the
      consultant, a dentist sold 20,000 shares and the Company remitted $79,463
      to the consultant. The $79,563 was reported as compensation as part of
      selling, general, and administrative expenses.

      Stock Option Plan

      In 1997, the Board of Directors approved the adoption of the 1997 Stock
      Option Plan. The 1997 Stock Option Plan provides for the grant of options
      to purchase up to 500,000 shares of the Company's common stock. Options
      may be granted to employees, officers, directors and consultants of the
      Company for the purchase of common stock of the Company at a price not
      less than the fair market value of the common stock on the date of the
      grant. In general, options become exercisable over a three-year period
      from the grant date and expire five years after the date of grant.

      NOTE F (continued)

      Options and warrants, in aggregate, to purchase 252,000 shares of common
      stock at prices ranging from $1 to $6 per share, were issued in aggregate
      to three officers and certain key personnel during the year ended December
      31, 1999.

      Options and warrants, in aggregate, to purchase 272,000 shares of common
      stock at prices ranging from $1.56 to $23 per share were issued during the
      year ended December 31, 1998.

      Stock-Based Compensation

      The Company has elected to follow Accounting Principles Board Opinion No.
      25 ("APB No. 25"), "Accounting for Stock Issued to Employees," and related
      interpretations in accounting for its stock options. Under APB No. 25,
      because the exercise price of the Company's employee stock options equals
      the market price of the underlying stock on the date of grant, no
      compensation expense is recognized. However, SFAS No. 123, "Accounting for
      Stock-Based Compensation," requires presentation of pro forma net income
      and earnings per share as if the Company had accounted for its employee
      stock options granted subsequent to December 31, 1994, under the fair
      value method of that statement. For purposes of pro forma disclosure, the
      estimated fair value of the options is amortized to expense over the
      vesting period. Under the fair value method, the Company's net loss and
      loss per share would have been increased by the amounts that follow:

                                              1999               1998
                                           -----------        -----------

      Net loss                             $(2,674,703)       $(1,103,000)
      Loss per common share                      $(.31)             $(.13)

      Because SFAS No. 123 is applicable only to options granted subsequent to
      December 31, 1994, and some options have a two- to five-year vesting
      period, the pro forma effect will not be fully reflected until 2001.

      The weighted-average fair value of the individual options granted during
      1999 and 1998 was estimated as $1.45 and $15.25, respectively, on the date
      of grant. The fair value for 1999 and 1998 was determined using a
      Black-Scholes option-pricing model with the following assumptions:

NOTE G - EMPLOYMENT CONTRACT

      In January 1998, the Company entered into a five-year employment contract
      with the Company's Chief Executive Officer providing for an increase in
      annual base compensation from $265,000 to $350,000, plus stock options and
      cash bonuses based upon the achievement of certain net income levels of
      the Company. These income levels were not achieved, and, therefore, the
      additional compensation provisions of the contract were not in effect for
      1998 and 1999.

NOTE H - LITIGATION

      Spinello Lawsuits

      On March 26, 1997, Milestone and Spintech commenced legal action in the
      United States District Court of New Jersey against Ronald Spinello, DDS,
      former Chairman and Director of Research of Spintech. In the complaint,
      plaintiffs seek recovery of compensatory and punitive damages for
      extortion and tortuous interference with existing and prospective contract
      and business relationships, a declaratory judgment that Dr. Spinello has
      no personal rights to certain technology developed while he was employed
      as Director of Research of Spintech relating to the design and production
      of ancillary components of its computer controlled local anesthetic
      delivery system, a declaratory judgment that plaintiffs have not breached
      Dr. Spinello's employment agreement or the agreement for the initial
      purchase by Milestone of a 65% equity interest in Spintech and injunctive
      relief. On May 21, 1997, Dr. Spinello filed an answer and counterclaim.

      As a result of various pretrial motions, the only claims remaining in the
      litigation with Dr. Spinello were Milestone's claims against Dr. Spinello
      and Dr. Spinello's counterclaim for unpaid salary for the period
      subsequent to his alleged wrongful termination, and a portion of his
      indemnification claim against Spintech.

      In January 2000, prior to trial, the Company agreed to settle with Dr.
      Spinello, the counterclaims asserted against Dr. Spinello and the claims
      asserted by Glenn Spinello. Various stipulations incorporating that
      settlement were executed in February 2000.

      Under the agreement, Dr. Spinello has assigned to Milestone any rights
      which he has to technology relating to "The Wand(R)" handpiece or
      technology developed while he was employed at Spintech and has agreed to
      cooperate in filing and to assign to Milestone any future patent
      applications covering that technology. Dr. Spinello and Glenn Spinello
      each also agreed to convey to Milestone all of his equity interests in
      Spintech. In return for the assignment of technology, the conveyance of
      Spintech equity and the resolution of all disputes between the parties,
      including the discontinuance with prejudice of pending legal actions,
      Milestone has paid $25,000 to Dr. Spinello and has agreed to issue to him
      a number of shares of Common Stock equal to the greater of 80,000 shares
      or shares with a market value of $80,000 and to issue to Glenn Spinello
      8,000 shares.

      Class Action Lawsuit

      In 1998, several class action lawsuits were commenced against the Company,
      certain present and former executive officers, one outside director and
      consultants in the United States District Court for the District of New
      Jersey. The District Judge before whom the cases are pending has entered
      an order consolidating all of the class actions into one consolidated
      action. The Complaints contain generally overlapping and similar
      allegations of violations of the Securities Exchange Act of 1934,
      including allegations that the Company and certain of the other defendants
      violated the Act by issuing false and misleading financial statements and
      disseminating misleading statements about, among other things, the demand
      for the Company's principal product, its expected sales growth, the
      acceptance of that product by dental professionals, shipments during
      certain time periods and misrepresentations as to third-party evaluations
      of the efficacy of the product through failure to disclose the issuance of
      stock options to certain consultants. On October 22, 1998, the District
      Judge entered an order appointing lead plaintiff to represent the
      interests of all class members. On March 28, 1999, the District Judge
      appointed lead counsel to represent the class. On April 28, 1999, the
      class filed a Consolidated and Amended Class Action Complaint, naming as
      defendants the Company and three present and former executive officer and
      director. The Consolidated Complaint alleges that the Company issued false
      and misleading statements concerning, among other things, certain studies
      and reports on the Company's products, the Company's backlog and the
      amount of reserve taken for returns. Milestone believes that the material
      allegations of the Consolidated Complaint does not state a cause of action
      under the Federal Securities Law and on May 21, 1999 served a motion to
      dismiss the Consolidated Complaint for failure to state a claim. The class
      has responded to the motion and the Company filed a reply. The Motion was
      submitted to the Court in September 1999, but no decision has yet been
      rendered. Instead, on March 1, 2000, the Court held oral argument on the
      Motion to Dismiss, at the end of which the court requested supplemental
      memoranda of law on one issue. The Supplemental Memoranda Of Law were
      filed on March 16 and 22, 2000. If the Motion to Dismiss is not granted,
      the company believes that the allegations contained in the class Action
      Complaint are without merit and it intends to vigorously defend the
      action. Specifically, Milestone believes that its financial statements
      presented fairly its results of operations, that the information which it
      has publicly disclosed did not contain any material misstatements or
      misrepresentations and that stock options issued to persons who published
      research reports were issued for other services for the Company,
      principally service as spokespersons and demonstrators of the Company's
      product. Further, the Company continues to believe that The Wand(R)
      embodies superior technology, is a major advance in dentistry and may
      ultimately become the accepted method for delivering local dental
      anesthesia.

NOTE H (continued)

      Derivative Action Lawsuit

      In February 1999, a purported owner of Milestone stock, commenced a
      derivative action on behalf of the Company, in the Court of Chancery of
      the State of Delaware in Newcastle County, against certain present and
      former executive officers and directors. In the action, plaintiff alleges
      that, based on the same facts as the class actions described above, the
      defendants engaged in violations of the securities laws, committed fraud
      and securities fraud, wasted corporate assets and damaged the Company's
      reputation. As a derivative action, even if the plaintiff is successful,
      any award, after deduction of plaintiff's costs and disbursements, would
      be payable to the Company. Nevertheless, Milestone believes that the
      material allegations of the complaint lack merit and intends to provide a
      legal defense for its present and former officers and directors in
      accordance with the indemnification provisions of its Certificate of
      Incorporation. Because the allegations of the Derivative Complaint are so
      closely tied to the allegations of the Class Complaint, the Derivative
      Plaintiff's counsel has agreed with the Company that no response to the
      Derivative Complaint is due until 60 days after the Court in the Class
      Action decides the motion to dismiss.

      Insurance Broker and Carrier

      In January 1999, the Company filed a complaint against its insurance
      broker (Frank Crystal Financial Services) and the two excess insurers
      [American Alliance and St. Paul] in the United States District Court for
      the District of New Jersey. American Alliance and St. Paul were in dispute
      with the Company because they claim that the Company did not timely submit
      the appropriate application. As a result, American Alliance refused to
      issue a policy and St. Paul, which issued a policy, has refused to cover
      the class actions described above. In April 1999, the Company reached a
      settlement of this action, as a result of which American Alliance issued
      the Excess Director's and Officer's Insurance Policy; the Company agreed
      that claims arising prior to the date of the policy were not covered by
      the policy and the parties reserved all of their arguments and positions
      with respect to any other coverage issues including those that resulted
      from the Consolidated and Amended Class Action Complaint referred to
      above.

NOTE H (continued)

      On June 24, 1999 American Alliance filed a complaint in the United States
      District Court for the Southern District of New York seeking a declaratory
      judgment that it is not liable under its policy for the claim asserted in
      the amended class complaint as well as the derivative complaint. The
      Company intends to vigorously defend against the American Alliance action
      and intends to move to dismiss that action. On July 9, 1999 the Company
      filed its own declaratory judgment action against American Alliance and
      St. Paul in the United States District Court for the District of New
      Jersey seeking a declaration that the claims asserted in the Consolidated
      Complaint in the Class Action and in the Derivative Action are covered by
      the Excess Director's and Officer's Insurance Policies. On August 4, 1999,
      the District Judge in New Jersey administratively terminated the Company's
      action until the previously filed New York Action was resolved or
      dismissed. Thereafter, the Company filed an answer and counterclaim in the
      New York Action seeking the same relief as it sought in its complaint in
      the New Jersey Action. Both American Alliance and the Company each
      requested leave from the Judge in the New York Action to make a motion for
      summary judgment and to dismiss the complaint, respectively. Instead,
      since any decision on the scope of coverage of the excess policies will,
      in large part, depend upon whether the Class Action complaint is
      dismissed, in whole or in part, the District Judge in the New York Action
      decided to hold in abeyance any action on American Alliance's complaint
      and Milestone's answer and counterclaim until a decision is rendered by
      the District Court in New Jersey in the Class Action.

      The valuation allowance has been established for those loss carryforwards
      and deductible temporary differences which are not presently considered
      more likely than not to be realizable.

      The provision for income taxes differs from the effective tax rate used in
      the financial statements as a result of current year net operating losses,
      the benefit of which has not been recognized in the current year.

      As of December 31, 1999, the Company had net operating loss carryforwards
      of approximately $23,535,000, which expire in 2007 through 2019.

NOTE I (continued)

      The utilization of loss carryforwards may be limited due to an ownership
      change as defined by Section 382 of the Internal Revenue Code.

      The Company and Spintech file separate Federal and State income tax
      returns.

NOTE J - LEASE COMMITMENTS

      In November 1996, the Company signed a five-year-and-one-month lease
      agreement for its corporate headquarters. In October 1999, the company's
      distribution center was consolidated from 2 units to one larger unit in
      the same business complex. Furthermore, in April 1999 the Company closed
      its Telemarketing Department, and was able to opt out of a three-year
      lease agreement set to expire March 2000.

      The Company also leases equipment under operating leases.

      The following represents approximate minimum rental payments under such
      leases:

NOTE K - RELATED PARTY TRANSACTIONS

      The Company paid approximately $131,632 and $239,000 in 1999 and 1998,
      respectively, to a law firm where one of the partners is also on the
      Company's Board of Directors. In addition, the law firm participated in
      the February 2000 private placement (Note O), purchasing $100,000 of 10%
      Senior Secured Promissory Notes and Warrants to purchase 14,286 shares of

                    NOTES TO FINANCIAL STATEMENTS (continued)

                           December 31, 1999 and 1998

NOTE L - COMMITMENTS AND CONTINGENCIES

      1.    The Company has consulting agreements with two dentists, which
            provide for aggregate base compensation of $181,000 per annum. At
            the discretion of management, these agreements were amended in 1999
            and subsequently renewed. Furthermore, an amendment to one agreement
            limited one dentist's opportunity to receive, during a specified
            four month period, up to $100,000 in compensation for the difference
            between the proceeds received from the sale of up to 20,000 shares
            of Milestone Common Stock and the value of the shares if they had
            been sold at $5 per share, net of commission (See Note F).

      2.    The Company has informal arrangements for the manufacture of its
            products by separate domestic manufacturers as follows: The
            Wand(R)unit and system kit by Tricor Systems, Inc. ("Tricor"); The
            Wand(R)disposable handpiece by Nypro Inc.; SplatrFree(TM)prophy
            angles by Team Technologies, Inc.; and luer lock needles by Becton
            Dickinson. Termination of the manufacturing relationship with any of
            the above manufacturers could significantly and adversely affect the
            Company's ability to produce and sell its products. Though alternate
            sources of supply exist and new manufacturing relationships could be
            established, the Company would need to recover its existing tools or
            have new tools produced. Establishment of new manufacturing
            relationships could involve significant expense and delay. Any
            curtailment or interruption of the supply, whether or not as a
            result of termination of such a relationship, would adversely affect
            the Company.

      3.    The Company made advances to Tricor to fund certain inventory
            purchases. Tricor repays such advances from future purchases by the
            Company. At December 31, 1999, the Company had advanced net amounts
            of $1,707,789. The advances included in inventory, net of reserves,
            were $1,230,428. The Company has received a security interest in
            certain Tricor assets.

      NOTE M - CONCENTRATIONS OF CREDIT RISK AND MAJOR CUSTOMERS

      Financial instruments which potentially subject the Company to
      concentrations of credit risk consist principally of cash and cash
      equivalents and trade accounts receivable. The Company places its cash
      with high credit quality institutions. In general, such investments exceed
      the FDIC insurance limit. Concentrations of credit risk with respect to
      trade accounts receivable are limited due to the fact that

NOTE M - (continued)

      there exists no individually significant customers, comprising the
      Company's customer base, and their dispersion across different geographic
      areas. The Company routinely assesses the financial strength of its
      customers and, as a consequence, believes that its trade accounts
      receivable credit risk exposure is limited. In 1998, the Company had two
      customers who accounted for 24.6% and 22.6% of the Company's total sales.
      In 1999, since the Company changed its domestic sales approach to a direct
      effort, it had one customer who accounted for 15.7% of the Company's total
      sales. Of the $940,000 generated from foreign sales, no country comprised
      a significant amount thereof.

NOTE N - ADVERTISING

      The Company expenses its advertising costs as they occur. Advertising
      expense for 1999 and 1998 was approximately $1,053,000 and $1,761,000,
      respectively.

NOTE O - SUBSEQUENT EVENTS

      Private Placement

      As of February 1, 2000, the Company concluded a $1 million institutional
      private placement of 10% Senior Secured Promissory Notes due June 30, 2001
      and Warrants to purchase 142,857 shares of Milestone Common Stock with
      Cumberland Associates LLC, Strategic Restructuring Partnership L.P., a
      former principal of Cumberland Associates, two officers of the Corporation
      and an affiliate of one of its directors. The Notes are secured by all
      present and future inventories of Milestone and are prepayable out of a
      portion of the proceeds generated by sales of "Wand(R)" units. The
      Warrants are exercisable at prices increasing from $1.75 per share in the
      first year of $7.00 per share in the fifth year, subject to anti-dilution
      protection in the event of stock dividends and certain capital changes.
      Purchasers of the Warrants were granted rights to participate in certain
      future security offerings by Milestone.

      In a related transaction, holders of Milestone's 3% Convertible Notes have
      agreed to convert all $2,250,000 of such notes into common stock at a
      $1.25 per share. (See Note E)

      Resolution of Dispute with Dr. Ronald Spinello

      In February 2000, Milestone entered into an agreement with Dr. Ronald
      Spinello and Glenn Spinello, formerly Director of Research and Vice
      President of Operations, respectively of Milestone's Spintech subsidiary,
      resolving all disputes between the parties.

      Under the agreement, Dr. Spinello has assigned to Milestone any rights
      which he has to technology relating to "The Wand(R)" handpiece or
      technology developed while he was employed at Spintech and has agreed to
      cooperate in filing and to assign to Milestone any future patent
      applications covering that technology. Dr. Spinello and Glenn Spinello
      each also agreed to convey to Milestone all of his equity interests in
      Spintech. In return for the assignment of technology, the conveyance of
      Spintech equity and the resolution of all disputes between the parties,
      including the discontinuance with prejudice of pending legal actions,
      Milestone has paid $25,000 to Dr. Spinello and has agreed to issue to him
      a number of shares of Common Stock equal to the greater of 80,000 shares
      or shares with a market value of $80,000 and to issue to Glenn Spinello
      8,000 shares.
